I'll admit that the original version of this questionquestion was confusing. It "conflated" two issues, watermarking and beaconing. There's no question about why the original was closed.
I removed one of the paragraphs (on "beaconing") and limited the scope of the question to "watermarking." I'm having trouble understanding why it remains closed,
Is the question acceptable for the site in its most recent form? If no, why not?
If yes, should I ask it as a "new" question?
Or should I go through the re-opening procedure, since it is an "old" question.
Below is a "clean" version of the most recent question:
What types of security are used for watermarking applications?
One use of "watermarking" is what I call "branding." That is, you put "watermarks" on your documents to identify them as yours, before sending them out over the "net." These watermarks are usually invisible, but perhaps they need not be, if all they do is to act as your "signature."
One danger of watermarking is "tampering." Another is "altering." What are standard or desirable security measures for these problems?
